What Slocum Hall Design Group, Llc does

Slocum Hall Design Group, LLC is a privately-held, Watertown, Massachusetts-based architecture and interior design firm founded in 2012 that serves affluent residential homeowners throughout the Greater Boston area, Cape & Islands, and broader New England (including New Hampshire and Vermont). The firm delivers four integrated service lines — Home Renovation Design, Home Addition Design, New Construction Design, and Residential Interior Design — plus ongoing Construction Administration, spanning from initial concept and site strategy through engineering coordination, material specification, and contractor oversight. Its portfolio demonstrates breadth across architectural styles including Modern Farmhouse, Cape Cod, Modern Prairie, Victorian, Colonial, Dutch Colonial, Craftsman, Mid-century Modern, Shingle-style, and Bungalow, with signature projects ranging from 6,000+ sq ft Weston Gambrel new builds to historic preservation work recognized by a Newton Preservation Award.

The business is a project-based professional services practice operating on a direct client engagement model, with fees structured as a not-to-exceed percentage of the stated construction budget and estimated hours provided for project completion. Acquisition channels include referrals, an active blog and Instagram presence (694 followers), earned media coverage in Northshore Home Magazine and New England Home Magazine, and recurring partnerships with builder firms (Hawthorn Builders, Concept Building, Hampden Design + Construction, Catalyst Development) and specialty collaborators (Eleven Interiors, Saltwoods, Symbio Design). The firm is led by Principal and Owner David Boronkay, with a small (1-10 employees) team including Senior Associate Interior Designer Alyssa Haggerty, Architect Jane Grover, and Designer Leana Taft.

The go-to-market motion is enterprise-style direct sales applied to a mid-market residential clientele, with the firm participating in industry events such as Boston Design Week and producing long-form video content (the 'Follow The Build' Vimeo series and a 5-part 'Reinventing the Prairie Style' collaboration with Boston Design Guide) to build brand visibility in the Boston-area design community. There is no disclosed revenue, funding, or external investment; the firm is independently owned with no parent company or subsidiaries evidenced.
